Gabriel Allon hasn't been back to Vienna since his wife and child died there in a terrorist bombing. But when his mentor in the Israeli intelligence agency dispatches him to the Austrian capitol to investigate a murderous explosion at the Wartime Claims and Inquiry Office, his presence alerts the attention of police officials who have reasons to stand in the way of his investigation. When a concentration camp survivor is killed who could link the father of Austria's next chancellor to Nazi atrocities and an ongoing coverup by the Catholic Church, Allon discovers another connection to the conspiracy, this one closer to his own past than he could ever have imagined. This is the third of Silva's thrillers featuring Allon, the art restorer who's also a spy (The Confessor and The English Assassin are the first two).
Art Restorer and Mossad spy Gabriel Allon is sent to Vienna to investigate a bombing that gravely injures an old friend who works for the WarTimes Claims and Inquiries. Along the way, he discovers his mother's past during the war and a man who would resort to anything to keep his identity a secret from the world.
